ABSTRACT Brain activity has multiple attributes, including electrical, metabolic, hemodynamic, and hormonal. Modern methods for studying brain functions such as PET (Positron Emission Tomography), fMRI (Functional Magnetic Resonance Imaging), and MEG (Magnetoencephalogram) are widely used by scientists. However, the EEG is a tool used for research and diagnosis due to its low cost, simplicity of use, mobility and the possibility of long-term monitoring of acquisition. To detect and interpret the relevant characteristics of these signals, each process is described by its temporal (EEG) and spatial (fMRI) scale. The present research focuses on conducting a bibliographic review on the integration of multimodal EEG-fMRI data that favors assessing its importance for the development of fusion algorithms and their use in the Cuban context. For this, documents with high rates of citations in the literature were analyzed, where precursor authors of the topics under analysis stand out. Multimodal EEG-fMRI studies generate multiple temporal and spatial data with high value for evidence-based medicine. Their integration provides added value in the search for new diagnostic methods, applying data mining, Deep learning and fusion algorithms. This work highlights the existence of low temporal resolution of fMRI and, on the other hand, the low spatial resolution of EEG, so the integration of both studies would increase the quality of their information.

RESUMEN La actividad cerebral tiene múltiples atributos, entre ellos los eléctricos, metabólicos, hemodinámicos y hormonales. Los métodos modernos para estudiar las funciones cerebrales como el PET (Tomografía por Emisión de Positrones), fMRI (Imagen de Resonancia Magnética Funcional) y MEG (Magnetoencefalograma) son ampliamente utilizados por los científicos. Sin embargo, el EEG es una herramienta utilizada para la investigación y diagnóstico debido a su bajo costo, simplicidad de uso, movilidad y la posibilidad de monitoreo a largo tiempo de adquisición. Para detectar e interpretar las características relevantes de estas señales, se describe cada proceso por su escala temporal (EEG) y espacial (fMRI). La presente investigación se enfoca en realizar una revisión bibliográfica sobre la integración de datos multimodales EEG-fMRI que propicie valorar su importancia para el desarrollo de algoritmos de fusión y su uso en el contexto cubano. Para ello se analizaron documentos con altos índices de citas en la literatura, donde se destacan autores precursores de los temas en análisis. Los estudios multimodales EEG-fMRI generan múltiples datos temporales y espaciales con alto valor para la medicina basada en evidencia. La integración de los mismos provee un valor agregado en la búsqueda de nuevos métodos diagnósticos, aplicando minería de datos, Deep learning y algoritmos de fusión. En este trabajo se pone de relieve la existencia de baja resolución temporal de fMRI y por otro lado la baja resolución espacial de EEG, por lo que la integración de ambos estudios aumentaría la calidad de su información.

Resumen Introducción: la capilaroscopia es un método no invasivo que permite observar la microvasculatura en el área periungueal. Los resultados informados pueden ser altamente variables entre distintos observadores. A lo largo del tiempo surgieron métodos cuantitativos y semicuantitativos para mejorar la reproducibilidad. Objetivos: conocer el nivel de acuerdo intra e interobservador al informar los diferentes patrones capilaroscópicos en individuos con diferente nivel de entrenamiento. Materiales y métodos: estudio de corte transversal. Participaron médicos reumatólogos especialistas y en formación que habían realizado previamente un curso virtual de capacitación en capilaroscopia. Recibieron 40 imágenes capilaroscópicas proyectadas en una presentación de PowerPoint y debían responder a través de un cuestionario digital. Se evaluó la concordancia de respuestas intra e interobservador. Resultados: se encontró un alto nivel de concordancia global con un kappa 0,66 IC 95% (0,63-0,70) p<0,0000. También en otros grupos como reumatólogos en formación: kappa 0,65 IC 95% (0,60-0,71) p=0,0000, y médicos reumatólogos: kappa 0,67 IC 95% (0,62-0,72) p=0,0000. Conclusiones: el nivel de concordancia encontrado fue globalmente alto, independientemente del nivel de entrenamiento de los profesionales, y de ser o no reumatólogo. La concordancia fue superior cuando se comparó a quienes tenían más de 4 años de experiencia en la realización de videocapilaroscopia.

Abstract Introduction: videoapillaroscopy is a non-invasive method that allows the observation of the microvasculature in the periungual area. Reported results can be highly variable between different observers. Over time, quantitative and semi-quantitative methods emerged to improve reproducibility. Objetives: to know the level of intra and interobserver agreement when reporting the different capillaroscopic patterns in individuals with different levels of training. Materials and methods: cross section study. Specialist rheumatologists and those in training who had previously completed a virtual capillaroscopy training course participated. They received 40 capillaroscopic images projected in a PowerPoint presentation and had to issue their response through a digital questionnaire. Concordance of intra and interobserver responses was evaluated. Results: a high level of global agreement was found with a kappa 0.66 CI 95% (0.63-0.70) p<0.0000, also in other groups such as rheumatologists in training: kappa 0.65 CI 95% (0.60-0.71) p=0.0000, physicians rheumatologists: kappa 0.67 95% CI (0.62-0.72) p=0.0000. Conclusions: the level of agreement found was globally high, regardless of the level of training of the professionals, and whether or not they were a rheumatologist. Concordance was higher when compared to those who had more than 4 years of experience performing videocapillaroscopy.

ABSTRACT Neuroscience is a field of science that studies the nervous system from neural functioning to behavior and how its different elements interact. The Cuban Neuroscience Centre is the main neuroscience research institution in the country, where different problems associated with the launch and management of neuroscience dataset processing queues has been identified. The processing of its databases is carried out manually on their HPC (High Performance Computer) servers due to technological and financial difficulties in accessing the services offered by international platforms, so researchers are forced to program instructions on the console to execute processing and analysis tasks. The aim of this research was to develop a tool that automates the queue management process and neurodata processing tasks for the BrainSSys platform. Python was used as programming language, PyQt5 and Sublime Text 3 as framework and code editor respectively. The result is a tool that automates the management of processing queues on the BrainSSys platform. The tests carried out determined the acceptance and functional evaluation of the tool, being in both cases of great value for the quality of the proposed solution.

RESUMEN Las neurociencias constituyen un campo de la ciencia que estudia el sistema nervioso desde el funcionamiento neuronal hasta el comportamiento y cómo sus diferentes elementos interactúan. El Centro de Neurociencias de Cuba es la principal institución de investigación de neurociencia en el país, donde fueron identificadas distintas problemáticas asociadas al lanzamiento y gestión de colas de procesamiento de datasets de neurociencias. El procesamiento que se desarrolla sobre sus bases de datos se realiza de forma manual en sus servidores de HPC (High Performance Computer) debido a dificultades tecnológicas y financieras para acceder a los servicios que ofrecen las plataformas internacionales, por lo que los investigadores se ven obligados a programar instrucciones en consola para ejecutar tareas de procesamiento y análisis. El objetivo de la presente investigación fue desarrollar una herramienta que automatice el proceso de gestión de colas y tareas de procesamiento de neurodatos para la plataforma BrainSSys. Se empleó Python como lenguaje de programación, PyQt5 como marco de trabajo y se utilizó el editor de código Sublime Text 3. Se obtuvo como resultado una herramienta que permite automatizar la gestión de las colas de procesamiento en la plataforma BrainSSys. Las pruebas realizadas determinaron la aceptación y la evaluación funcional de la herramienta, siendo en ambos casos de gran valor para la calidad de la propuesta solución.

Abstract: Paraneoplastic syndromes are defined as a set of signs and symptoms that appear in distant locations from the underlying malignancy or its metastases in the oncological patient, secondary to the secretion of substances by the tumor or by the development of antibodies directed against tumor antigens, which develop a cross-reaction with other tissues. Among the cancers that most frequently develop these syndromes is lung cancer. The presence of some of these paraneoplastic syndromes can guide us to know the histological line of lung cancer. Similarly, many of these syndromes tend to appear before diagnosis, and may even indicate the prognosis of this cancer.

Resumen: Los síndromes paraneoplásicos se definen como el conjunto de signos y síntomas que aparecen en sitios distantes a la neoplasia maligna primaria o sus metástasis en el paciente oncológico, secundario a la secreción de sustancias por parte del tumor o por el desarrollo de anticuerpos dirigidos contra antígenos tumorales, los cuales desarrollan una reacción cruzada con otros tejidos. Dentro de los cánceres que con mayor frecuencia desarrollan estos síndromes se encuentra el cáncer pulmonar. La presencia de algunos de estos síndromes paraneoplásicos puede orientarnos a conocer la estirpe histológica del cáncer pulmonar. De igual forma, muchos de estos síndromes tienden a presentarse antes del diagnóstico, e incluso, algunos pueden indicarnos el pronóstico de dicho cáncer.

Abstract Background We aimed to assess the feasibility of using supraglottic devices as an alternative to orotracheal intubation for airway management during anesthesia for endovascular treatment of unruptured intracranial aneurisms in our department over a nine-year period. Methods Retrospective single center analysis of cases (2010-2018). Primary outcomes: airway management (supraglottic device repositioning, need for switch to orotracheal intubation, airway complications). Secondary outcomes: aneurysm complexity, history of subarachnoid hemorrhage, hemodynamic monitoring, and perioperative complications. Results We included 187 patients in two groups: supraglottic device 130 (69.5%) and orotracheal intubation 57 (30.5%). No adverse incidents were recorded in 97% of the cases. Three supraglottic device patients required supraglottic device repositioning and 1 supraglottic device patient required orotracheal intubation due to inadequate ventilation. Three orotracheal intubation patients had a bronchospasm or laryngospasm during awakening. Forty-five patients (24.1%) had complex aneurysms or a history of subarachnoid hemorrhage. Thirty-three of them (73.3%) required orotracheal intubation compared to 24 of the 142 (16.9%) with non-complex aneurysms. Two patients in each group died during early postoperative recovery. Two in each group also had intraoperative bleeding. A post-hoc analysis showed that orotracheal intubation was used in 55 patients (44%) in 2010 through 2014 and 2 (3.2%) in 2015 through 2018, parallel to a trend toward less invasive blood pressure monitoring from the earlier to the later period from 34 (27.2%) cases to 5 (8.2%). Conclusion Supraglottic device, like other less invasiveness protocols, can be considered a feasible alternative airway management approach in selected patients proposed for endovascular treatment of unruptured intracranial aneurisms.

Abstract: Melanoma is the type of skin cancer with highest mortality worldwide due to its metastatic potential. In the recent years there has been an increasing incidence of melanoma worldwide, including in Mexico. There are several mechanisms involved in the pathogenesis of melanoma making it difficult to develop specific therapies. However, recently immunotherapy has been taking interest in treatment of melanoma, due to the introduction of inhibitors of immune checkpoints, this type of therapy has significantly improved long-term survival in patients with advanced melanoma. Therefore, the scientific community has focused on comparing side effects and efficacy versus standardized treatments, until today no better outcomes have been found, on the contrary patients can present an immune related response due to their action mechanism. Unfortunately, only a few patients have shown a satisfactory response to this type of therapy. This article reviews the results of the most recent studies conducted with checkpoint inhibitors, recommended doses, and frequency of adverse effects on immune system.

Resumen: El melanoma es el cáncer de piel con mayor mortalidad en el mundo, gracias a su alto potencial metastásico. En los últimos años se ha visto un aumento en su incidencia de manera global, incluyendo a México. Muchos son los mecanismos involucrados en la patogenia del melanoma, por lo que ha sido difícil el desarrollo de terapias específicas para su curación. Sin embargo, desde hace algunos años la inmunoterapia ha ido retomando interés en el melanoma, gracias a la introducción de los inhibidores de los puntos de control inmunitario. Estos fármacos han logrado de manera significativa mejorar la supervivencia a largo plazo de pacientes con melanoma avanzado. Desde entonces, la comunidad científica se ha enfocado en reconocer sus efectos y comparar su eficacia con tratamientos previamente utilizados, que hasta el momento no habían logrado obtener los mismos resultados. Desafortunadamente, cierto número de pacientes continúa sin lograr una respuesta satisfactoria, sin olvidar los múltiples efectos adversos inmunitarios asociados. En este artículo de revisión se describen los resultados de los estudios más recientes realizados con inhibidores de puntos de control, las dosis recomendadas y la frecuencia de sus efectos adversos inmunológicos.

ABSTRACT Background: Severe pneumonia is the most common cause of intensive care unit (ICU) admission and death due to novel coronavirus (SARS-CoV-2) respiratory disease (COVID-19). Due to its rapid outbreak, units for the evaluation of febrile patients in the pre-hospital setting were created. Objective: The objective of the study was to develop a sensitive and simple tool to assess the risk of pneumonia in COVID-19 patients and thus select which patients would require a chest imaging study. Materials and Methods: We conducted a cross-sectional study in a cohort of individuals with suspected COVID-19 evaluated in a public academic healthcare center in Buenos Aires city. All adult patients with positive RT-PCR assay for SARS-COV2 between April 24 and May 19 of 2020 were included in the study. Pneumonia was defined as the presence of compatible signs and symptoms with imaging confirmation. Univariate and multivariate logistic regression was performed. A risk indicator score was developed. Results: One hundred and forty-eight patients were included, 71 (48%) received the diagnosis of pneumonia. The final clinical model included four variables: age ≥ 40 years, cough, absence of sore throat, and respiratory rate ≥ 22. To create the score, we assigned values to the variables according to their ORs: 2 points for respiratory rate ≥ 22 and 1 point to the other variables. The AUC of the ROC curve was 0.80 (CI 95% 0.73-0.86). A cutoff value of 2 showed a sensitivity of 95.7% and a specificity of 43.24%. Conclusion: This sensible score may improve the risk stratification of COVID-19 patients in the pre-hospital setting. (REV INVEST CLIN. 2021;73(1):52-8)

RESUMO Racional: A cirurgia laparoscópica tem sido gradualmente aceita como opção para o tratamento cirúrgico do câncer gástrico. Ainda existem pontos controversos ou situações eventualmente associadas a dificuldades intra-operatórias ou complicações pós-operatórias. Objetivo: Estabelecer a relação entre as dificuldades durante a execução da gastrectomia total e a ocorrência de eventuais complicações pós-operatórias. Método: Foram revisados os protocolos operatórios e a evolução pós-operatória de 74 pacientes operados por câncer gástrico, submetidos à gastrectomia total laparoscópica (critérios de inclusão). Foram analisadas as dificuldades intraoperatórias registradas no protocolo operatório e as complicações pós-operatórias de natureza cirúrgica (critérios de inclusão). As complicações médicas pós-operatórias foram excluídas (critérios de exclusão). Para a discussão, foi realizada extensa revisão bibliográfica. Resultados: Dificuldades ou complicações intraoperatórias relatadas corresponderam a 33/74 e destas 18 (54,5%) foram relacionadas com complicações pós-operatórias e seis absolutamente inesperadas. As mais frequentes foram vazamentos da anastomose e do coto duodenal; no entretanto, outras complicações raras foram observadas. Sete foram tratados com medidas conservadoras e 17 (22,9%) necessitaram de re-exploração cirúrgica, com mortalidade pós-operatória de dois pacientes (2,7%). Conclusão: Aprendemos que existem complicações infrequentes e inesperadas; a equipe de tratamento deve estar atenta e diante da suspeita de complicação, decisão apropriada pode incluir uma nova exploração precoce. Finalmente, após a experiência relatada, algumas complicações devem ser evitadas.

ABSTRACT Background: Laparoscopic surgery has been gradually accepted as an option for the surgical treatment ofgastric cancer. There are still points that are controversial or situations that are eventually associated with intra-operative difficulties or postoperative complications. Aim: To establish the relationship between the difficulties during the execution of total gastrectomy and the occurrence of eventual postoperative complications. Method: The operative protocols and postoperative evolution of 74 patients operated for gastriccancer, who were subjected to laparoscopic total gastrectomy (inclusion criteria) were reviewed. The intraoperative difficulties recorded in the operative protocol and postoperative complications of a surgical nature wereanalyzed (inclusion criteria). Postoperative medical complications were excluded (exclusion criteria). For the discussion, an extensive bibliographical review was carried out. Results: Intra-operative difficulties or complications reported correspond to 33/74 and of these; 18 events (54.5%) were related to postoperative complications and six were absolutely unexpected. The more frequent were leaks of the anastomosis and leaks of the duodenal stump; however, other rare complications were observed. Seven were managed with conservative measures and 17 (22.9%) required surgical re-exploration, with a postoperative mortality of two patients (2.7%). Conclusion: We have learned that there are infrequent and unexpected complications; the treating team must be mindful of and, in front of suspicion of complications, anappropriate decision must be done which includes early re-exploration. Finally, after the experience reported, some complications should be avoided.

ABSTRACT This study is an attempt to approach the cultural habits and practices of three groups of university students attached to the University of Cuenca, the University of Azuay and the National University of Education of Ecuador. This work is part of a broader research project that aims to explore the cognitive support of students in essential aspects of the subject, at the beginning of the semester and its verification at the end, while discovering their habits and educational cultural practices. This proposal is not conceived from a quantitative conception but as a teaching experience that aims to use cultural manifestations as a strategy in the teaching-learning process. In order to achieve this goal, an instrument has been elaborated in two modules of contents: an identification one dedicated to certain sociodemographic characteristics of the students and another focused on the study of cultural habits and practices. The results obtained in this investigation show in general lines, the existence of an increase in certain cultural habits and practices and highlights certain weaknesses in this university population.

RESUMEN Este estudio es un intento de aproximación a los hábitos y prácticas culturales entre grupos de estudiantes universitarios adscriptos a la Universidad de Cuenca, la Universidad del Azuay y la Universidad Nacional de Educación de Ecuador. Este trabajo forma parte un proyecto de investigación más amplio que tiene como finalidad explorar sobre el soporte cognitivo del alumnado en aspectos esenciales de la asignatura, en el momento inicial del semestre y su constatación a la finalización, al tiempo que descubrir sus hábitos y prácticas educativo-culturales. Esta propuesta no es concebida desde una concepción cuantitativa sino como una experiencia docente que pretende utilizar las manifestaciones culturales como estrategia en el proceso de enseñanza-aprendizaje. Para alcanzar ese objetivo se ha elaborado un instrumento articulado en dos módulos de contenidos: uno identificativo dedicado a determinadas características sociodemográficas del alumnado y otro centrado en el estudio de los hábitos y prácticas culturales. Los resultados obtenidos en esta investigación muestran, en líneas generales, la existencia de un incremento en determinados hábitos y prácticas culturales y ponen en evidencia explícitas debilidades en esta población universitaria analizada.

Abstract Diabetes mellitus type 2 (DM2) is a chronic and multifactorial disease that requires an integral treatment throughout the life of the patient and in need of constant adjustments according to specific requirements of each patient. It is well established that weight loss in diabetic patients may delay the progression of the disease or even delay its onset. In addition to being a beneficial factor in the treatment goals of diabetic patients, weight reduction can achieve clinically significant changes in serum glucose, glycated hemoglobin (HbA1c) and triglyceride levels. Evidence-based recommendations are currently aimed at pharmacological, surgical and lifestyle changes in the management of obesity as part of the comprehensive treatment of patients with diabetes mellitus type 2. Traditional pharmacological treatments for diabetes mellitus type 2 may further increase weight and this may decrease the benefits of adequate glycemic control. It’s important to identify the interference of each drug group on weight.

Resumen La diabetes mellitus tipo 2 es una enfermedad multifactorial y de carácter crónico que requiere un tratamiento integral a lo largo de la vida del paciente y con necesidad de ajustes constantes de acuerdo con los requerimientos específicos de cada paciente. Se ha identificado que la disminución de peso en pacientes diabéticos puede retrasar la progresión de la enfermedad e incluso retrasar o evitar su aparición. Además de ser un factor benéfico en las metas de tratamiento de los pacientes diabéticos, la disminución del peso puede lograr cambios clínicamente significativos en las concentraciones totales de glucosa sérica, hemoglobina glucosilada (HbA1C) y en las concentraciones de triglicéridos. En la actualidad las recomendaciones basadas en evidencia están dirigidas a la intervención farmacológica, quirúrgica y cambios en el estilo de vida en el manejo de la obesidad como parte del tratamiento integral de los pacientes con diabetes mellitus tipo 2. Los tratamientos farmacológicos tradicionales contra la diabetes mellitus tipo 2 pueden aumentar aún más el peso y esto puede disminuir los beneficios del control glucémico adecuado. Es importante identificar la injerencia de cada grupo de fármacos en el peso.

ABSTRACT The continuous growth of the commercial and industrial sector in Ecuador, has brought with it a heavy transport area with a sustained increase in its activities both locally and internationally. The main objective of this work is to analyze the factors that impact on the quality of service of the heavy transport companies in Ecuador. The methodological approach to this research is mixed as it contains both qualitative and quantitative research methods. In order to know their current situation and propose some alternative solutions, surveys and interviews were applied to important companies in the heavy transport sector and to the users of its service. The results include the lack of control in the delivery times of the commodity transported and the low safety rates in the merchandise transport service. This has made the majority of companies consider a change in their transport service provider that complies with the requested requirements. Finally, it is concluded that the heavy transport service can be improved through continuous improvement techniques and process standardization.

RESUMEN El continuo crecimiento del sector comercial e industrial en el Ecuador ha traído consigo para el área de transporte pesado un incremento sostenido de sus actividades tanto a nivel local como intercantonal. El objetivo de este trabajo se basa en analizar los factores que afectan la calidad del servicio de las empresas de transporte pesado en Ecuador con la finalidad de conocer su situación actual y proponer soluciones alternas. El enfoque metodológico de esta investigación es mixto ya que contiene métodos de investigación tanto cualitativos como cuantitativos Se aplicaron encuestas y entrevistas a importantes empresas del sector de transporte pesado y a usuarios del servicio. Como resultados se destacan los bajos índices de seguridad en el servicio de transporte de mercadería y la falta de control en los tiempos de entrega de la carga transportada, como consecuencia, la mayoría de empresas tiene disposición de cambiar de proveedor de servicios de transporte que cumpla con los requisitos solicitados. Finalmente se concluye que el servicio de transporte pesado se puede mejorar mediante técnicas de mejora continua y estandarización de los procesos.

ABSTRACT The following written memory is based from a conception dialectical materialist on the significance that has the formation of competitions in the Ecuadorian educators to contribute in favor of a society more productive and less consumistas, based on the innovation and the ethics in the contemporary context of the education. For it the present work approaches the necessity of the human performance starting from a pertinent conception that requires the development of competitions, those that incorporate from the formation and the empírea to assume more and more complex and global processes. In a same way, the context of a society marked by the access to the knowledge needs him to be acquired systems of knowledge that incorporate the fellow competitions that you/they allow him to be inserted in a more and more competitive Word for the development of a more holistic and humanist posture.

RESUMEN La siguiente memoria escrita se fundamenta desde una concepción dialéctico materialista sobre la significación que tiene la formación de competencias en los educadores ecuatorianos para contribuir en favor de una sociedad más productiva y menos consumistas, basada en la innovación y la ética en el contexto contemporáneo de la educación. Para ello el presente trabajo aborda la necesidad de la actuación humana a partir de una concepción pertinente que requiere el desarrollo de competencias, las que se incorporan desde la formación y la empírea para asumir procesos cada vez más complejos y globales. De igual manera, el contexto de una sociedad marcada por el acceso al conocimiento necesita que se adquiera sistemas de conocimientos que le incorporen al sujeto competencias que le permitan insertarse en un mundo cada vez más competitivo para el desarrollo de una postura más holística y humanista.

RESUMO O objetivo deste trabalho foi utilizar o método da Predição dos Parâmetros da função Weibull 3P (Três Parâmetros) para a projeção da distribuição diamétrica de um Fragmento de Floresta Ombrófila Mista, comparando os resultados com projeções geradas pelos métodos Matriz de Transição e Razão de Movimentos. Os dados são oriundos de 100 parcelas permanentes de 2.500 m² (50 m x 50 m) instaladas na Floresta Nacional de Irati, Estado do Paraná e medidas nos anos de 2002, 2005, 2008 e 2011. Para o método da Predição dos Parâmetros foram ajustados modelos (pelo método stepwise) para projeção de 3, 6 e 9 anos cujas variáveis dependentes foram os parâmetros da função Weibull 3P b e c (o parâmetro a foi fixado em 10,02 cm, correspondente ao valor do diâmetro mínimo mensurado) e como variáveis independentes foram testadas o N.ha-1, G.ha-1, dg, dmin, diâmetros percentis (dP), dmax e suas transformações (inversa, logarítmica e quadrática). Um modelo de sobrevivência foi ajustado para projetar o número de árvores. As projeções obtidas pelo método da Predição dos Parâmetros para 2008 e 2011 foram comparadas com as projeções geradas pelos métodos da Matriz de Transição e Razão de Movimento utilizando-se o teste Kolmogorov-Smirnov (K-S) e o Índice de Reynolds (IR). O desempenho dos ajustes dos modelos foi avaliado pelo índice de Schlaegel (IA) e o erro padrão de estimativa em percentagem (SYX%). Os resultados indicaram bons ajustes para o método da Predição dos Parâmetros da função Weibull. Na comparação com o da Matriz de Transição e Razão de Movimento, o método testado apresentou os melhores resultados de acordo com o teste K-S, porém de acordo com IR, a melhor performance foi verificada pelo método da Matriz da Transição. Nos três métodos analisados houve aderência entre distribuições observadas e estimadas de acordo com o teste K-S.

ABSTRACT The objective of this study was to use the 3P (Three Parameters) Weibull Parameter Prediction method to predict the diameter distribution in a Mixed Ombrophilous forest fragment, comparing the results with predictions generated by the Transition Matrix and Movement Ratio methods. The data come from 100 permanent plots of 2,500 m² (50 m x 50 m) established in the National Forest of Irati, in Parana state, measured in the years of 2002, 2005, 2008 and 2011. For the Parameter Prediction method it has been fitted (stepwise) models for predictions for 3, 6 and 9 years, using as dependent variables, the 3P Weibull parameters b and c (a parameter was set at 10.02 cm corresponding to the minimum value of diameter measured) and, as the independent variables were tested N.ha-1, G.ha-1, dg, dmin, percentile diameters (dP), dmax and their transformations (inverse, logarithmic and quadratic). A survival model was adjusted to predict the future number of trees. The predictions obtained by the Parameter Prediction method for 2008 and 2011 have been compared with the predictions generated by the Transition Matrix and Movement Ratio methods using the Kolmogorov-Smirnov (KS) and Reynolds index (RI). The models were evaluated by the Schlaegel index (I.A.) and relative standard error of estimate in percentage (SYX%). The results indicated good fits for the 3P Weibull Parameter Prediction method. In comparison with the Transition Matrix and Movement Ratio approach, this method showed the best results according to the KS test, but according to IR, the best performance was found by the Transition Matrix method. All three methods evaluated had adherence between observed and theoretical distributions according to the KS test.
